Intelligentsia Coffee Jamsil is on the fifth floor of Lotte World Mall in Songpa-gu, Seoul, and sells specialty coffee and desserts. The roasts lean light, so the acidity is pronounced, and cortados and lattes suit the coffee better than an americano. The seating is fairly extensive, so on weekdays there is room to sit. On weekends the seats fill up and the store is on the small side.
